To all whom it may concern.-

Be it known that I, VVILLIAM GEORGE BEATTY, a British subject, and resident of the town of Fergus, in the county of WelL ington and Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Carriers and I hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to a carrier of that type in which the load is lifted by a hoisting pulley attached at one end to a rock shaft, on which is mounted a lock adapted to engage a stop block secured to the trackwhy, and the other end of which is adapted to pass over a hoisting pulley and between a pair of rope gripping jaws, which open and close in parallel planes, one of the objects of the invention being to provide an adjust-able connection between the lock and the jaws to accurately adjust them to the diameter of the rope passing between them.

A further object of the invention to provide a swiveled connection for the hoisting pulley which will enable it to automatically adapt itself to the direction of the hoisting rope from the load to the hoisting pulley, and to provide an idler to maintain the alinement of the rope from the hoisting pulley to the jaws.

A still further object of the invention is to provide the carrier with a detent to prevent the lock oscillating to close the jaws during the hoisting of the load and with a trip to release the detent for the oscillation of the lock to close the jaws when the load is hoisted to its elevated position.

For an understanding of the invention reference is to be had to the following description and accompanying drawings, in which:

Figure 1, is a side elevational View of-the carrier with the parts positioned for the hoisting of the load,

Fig. 2, is an end View of the same,

Fig. 3, is a view similar to 1 looking at the carrier from the opposite side,

Fig. 4c, is a top plan view of the carrier,

Fig. 5, is a longitudinal section of the carrier with the parts shown in Fig. l, and

Fig. 6, is a similar view to Fig. 5 with the rope gripping jaws closed.

ike characters of reference refer to like parts throughout the specification and drawings.

The operating parts of the carrier are mounted in a frame a, connected by a swivel b to the car 0, the wheels, (Z, of which are adapted to travel on the track rail 6, on the under side of which is a stop block f. The general principle of the construction of these parts is embodied in carriers commonly used in barn equipment. I

Between the sides of the frame a, near the top at one end thereof, is journaled a rock shaft 9, on which is mounted a lock 71 adapted to engage with the stop block f, when the car comes into position with it for the hoisting of the load, and mounted in the frame a adjacent to the lock it is a pin 11, on which is mounted a rocking detent j.

The detent j is preferably of a U-shape, and its forks j are adapted to engage the lock 72/ and hold it in a set position to maintain the rope gripping jaws opened for the movement of the hoisting rope during the lifting of the load.

Extending outwardly from the detent j is an arm j", to which is attached a trip rope j Fulcrumed to the frame a is a trip lever 71:, and pivoted to the lever is between its fulcrum and its free end are two arms Z, which are pivotally connected at or near their upper ends with the arms j of the de tent Passing through the frame a at the opposite end to the rock shaft 9 is a bolt m, and in front of the bolt m is a second bolt m, which passes through the frame a in the same plane as the bolt m. Suspended from the bolts m, m, are two sets oflinks 0, 0, and each of the links 0, 0', has two sets of eyes p, 10, in oblique alinement to receive the pintles q, of the rope gripping jaws r, 1*, respectively, which owing to this construction open and close in parallel planes. Pivotally connectedto the links 0 is a U-shaped coupling member 8, having an axial bore 8 through its head 8, for a draw bar If.

Onev extremity t" of the draw bar is of a hookshaped formation, and engages in an eye it" in the lock It, and the other extremity t, is screw threaded and extends, through the bore 8. V

The screw threaded extremity t" of the.

draw bar is provided with adjusting nuts it, a, arran ed on opposite sides of the head 8" to adjust the jaws to the size of the rope tightly against a rope of the largest size, or they can be adjusted to close tightly against a rope of any diameter intermediate the largest and smallest sizes.

To enable the hoisting pulley to automatically adapt itself to the direction of the hoisting rope and its entrance to the jaws, the housing 4; of the hoisting pulley o is provided with a sleeve e" through which passes a bolt or pin w mounted in the frame a.

" This swiveled arrangement for the hoisting pulley enables it to automatically adapt itself to the direction of the hoisting rope, which direction constantly varies according to the size of the loads which it lifts. Interposed between the hoisting pulley and the rope gripping jaws is an idler so, journaled in the frame a, and arranged transversely to the hoisting pulley with its grooved perimeter substantially in the same plane as the top of the hoisting pulley and the ropeway between the jaws.

' Fixed on the rock shaft 9 on the opposite side of the frame a to the hoisting pulley o is an arm y, having a pivoted eye y, to which the fixed end of the hoisting rope is attached.

As shown in the drawings the hoisting rope extends from the arm 3 to the hoisting pulley o, and passes between the rope gripping jaws r, 7". When the hoisting rope elevates the sling pulleys .2, to engage with the tripping lever k, the latter releases the detent j from engagement with the lock,

which then oscillates with the rock shaft and closes the rope gripping jaws against the rope, the rock shaft being rotated by the weight of the load on the arm 3 from the position shown in Fig. 5 to that shown in Fig. 6. The rope gripping jaws and their related parts including the stop lock it remain in the position shown in Fig. 6 until they are again restored to the position shown in Fig. 5, by the lock it coming into engage ment with the stop block f on the return of the carrier to the hoisting position.

' l/Vhen the rope gripping jaws are closed against the hoisting rope the movement of the latter in the lowering direction is prevented and the carrier can then convey the load to where it is to be dumped. On the return of the carrier to the hoisting position its momentum brings the lock 71, into forcible engagement with the stop block f, and the latter then upsets the lock it from the position shown in Fig. 6 to that shown in Fig.

5, the rock shaft being at that time relieved of the weight of the load. The; upsetting of the loci-1 it actuates its related parts to reopen the rope gripping jaws, and the hoisting rope can then descend for the next load.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A carrier including an oscillating look, a pair of rope gripping jaws which open and close in parallel planes, and an adjustable connection between the lock and the jaws to regulate their movement to the diameter of the rope passing through them.

2. A carrier comprising a pair of rope gripping jaws which open and close in parallel planes, a rock shaft, an oscillating locl: mounted on the rock shaft and connected with the jaws to open and close them, and a swiveled hoisting pulley to automatically adapt itself with relation to the direction of the hoisting rope from its connection with the rock shaft to the entrance of said jaws.

3. A carrier comprising a pair of rope gripping jaws which open and close in parallel planes, a rock shaft, an oscillating lock mounted on the rock shaft and connected with the jaws to open and close them, a swiveled hoisting pulley to automatically adapt itself with relation to the direction of the hoisting rope from its connection with the rock shaft to the entrance of said jaws,

and an idler interposed between the jaws and the hoisting pulley to maintain the aliuement of the rope.

i. A carrier including a pair of rope gripping jaws, an oscillating lock connected with the jaws to open and close them, a detent holding the lock and jaws in an open position, and a lever, pivoted to the carrier and connected with the detent, engaged by the load when raised to automatically release the detent from the lock for the closing movement of the aws.

5. A carrier including a rock shaft, a lock fixed thereon, a pair of rope gripping jaws connected with tl e loclr and opened and closed by it as it moves with the rock shaft, a bifurcated detent to hold the lock and jaws in open position, and an arm for actuating the detent to release it from the lock.
